## About "device" in BIP39

- "device" has 6 letters, but the first four, **"devi"**, already identify it, because **"dev"** also begins [develop](/bip39-word/develop/) and [devote](/bip39-word/devote/).
- **"devi"** is unique only within the English list: it also begins deviner in the [French list](/french/) and devido in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "device" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #16 (word 7 of 12). Every official vector passes the [checksum checker](/bip39-checksum-checker/), and [How BIP39 works](/how-bip39-works/) shows how the entropy turns into such words.
